摘要：
A biometric detection module including a light source module, a detection region and a control module is provided. The light source module is configured to emit green light, red light and IR light in a time division manner to illuminate a skin surface. The detection region is configured to detect penetration light emitted from the light source module for illuminating the skin surface and passing though body tissues to correspondingly generate a green light signal, a red light signal and an IR light signal. The control module is configured to determine a filtering parameter according to the green light signal to accordingly filter the red light signal and the IR light signal, and calculate a biometric characteristic according to at least one of the green light signal, a filtered red light signal and a filtered IR light signal.一種生理偵測模組，包含一光源模組、一感測區塊及一控制模組。該光源模組用以分時地發出綠光、紅光及紅外光以照射一皮膚表面。該感測區塊用以感測該光源模組所發出照射該皮膚表面並經過身體組織之穿透光以相對產生一綠光訊號、一紅光訊號及一紅外光訊號。該控制模組用以根據該綠光訊號決定一濾波參數以對該紅光訊號及該紅外光訊號進行濾波，並根據該綠光訊號、一濾波後紅光訊號及一濾波後紅外光訊號至少其中之一計算一生理特徵。
